About 1,600 clinical research studies are under way at the Clinical Center, most of them sponsored by the institutes and centers at NIH. These different institutes, centers and divisions study diseases such as cancer, AIDS, heart trouble, eye problems, dental problems, depression and nerve diseases, to name just a few.

Clinical studies are medical research studies (or protocols) in which human volunteers participate. Clinical trials are studies developing or investigating new treatments and medications for diseases and conditions. Natural history studies investigate normal human biology and the development of a particular disease. Screening studies determine if individuals may be suitable candidates for inclusion in a particular study. Training studies provide an opportunity for staff physicians and other health-care professionals to follow particular types of patients. Please visit our database of studies for details on those studies. Or speak with one of the specialists in our patient recruitment office, 1-800-411-1222.

Have you been diagnosed with cancer of the head and neck? Researchers at the National Institute on Deafness and Other Communication Disorders (NIDCD) are investigating the effectiveness of atorvastatin (40 mg) at reducing the incidence of hearing loss in patients treated with cisplatin-based chemotherapy for head and neck cancer.

January was officially proclaimed over 50 years ago, to applaud the undeniable generosity and importance of the U.S. blood donor population. This time of year, with the increase in seasonal illnesses, holiday travel, and inclement weather, voluntary blood donation drops significantly. The need for blood does not.
We are indebted to those donors, a selfless, select group of individuals, who continue to commit to maintaining the Nation’s blood supply; less than 3 % of the eligible American population donates blood. Please help us recognize these heroes and consider joining their “worthy ranks” by scheduling a blood donation – even just one – this year. Patients are counting on it.

📣 Does your teen have autism? Researchers at NIMH want to hear from you.

They’re studying how the brain responds to language and sound, and how different areas of the brain communicate.

📍 Teens ages 11–17 with autism spectrum disorder (ASD) may qualify for this research study at the NIH Clinical Center in Bethesda, MD. Some study activities may be completed virtually.

💰 Participation is free, and families may receive up to $1,000 in compensation.

📞 To learn more or enroll, call 833-JOIN-NIH (TTY: 711) and mention Study #20-M-0159. go.nih.gov/w9w5NzJ

An experimental treatment at the NIH for patients with severe aplastic anemia (a condition where your bone marrow, the body's blood cell factory, stops making enough new blood cells) resulted in a 94% survival rate without complications following transplantation. The treatment, which deploys an expanded umbilical cord blood approach known as omidubicel, was recently approved by the U.S. Food and Drug Administration for use against severe aplastic anemia for patients without options to receive donor hematopoietic stem cell transplantation.

Do you know if you have sickle cell trait? Doctors at the NIH seek volunteers with or without sickle cell trait to study how genes impact our blood vessels. This information may lead to the development of new treatments for blood diseases, including sickle cell disease and malaria.

Heart disease is the leading cause of death and disability in the United States. Researchers want to evaluate if dietary lipids have an effect on decreasing your cardiovascular risk. Healthy volunteers at least 18 years old who have no history of cardiovascular disease are needed for a research study at the NIH Clinical Center. https://bit.ly/3XEJnMr

Are you in good physical and mental health?

Join an NIMH Research Volunteer Study! Enrolling ages 18 to 70.

The goal of this study is to pre-qualify volunteers to participate in NIMH research studies. This study has two parts. Part one is online to sign up and answer questions (takes about 45 minutes). Part two is by invitation for in-person visits to the NIH Clinical Center in Bethesda, MD for psychological assessments; physical, blood and urine tests; and optional brain scans. No cost to participate. Compensation may be provided up to $410 for NIH visits.
